' Application led January 9, 1924.

To all whom z' may concern:

Be it known that I, FRED M. SPAYD, a citizen of the United States,residing at Van Wert, in the county of Van lVert and State of Ohio, haveinvented certain new and useful Improvements in Laths; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to laths for internal or external use in applyingplaster, stucco, or the like, and the objectv is to improve upon theconstruction of ordinary wooden laths to such an extent as to providefor more effective keying of the plastic material between the lathswhich are laid in the usual spaced relation.

With the foregoing in view, resides in the novel subject after describedand claimed, being supplemented by the drawing.

Figure l. is an elevation of a partly completed wall embodying theimproved laths.

Figure 2 is a horizontal section on line 2-2 of Fig. l.

Figures 3 and 4.- are vertical sections 0n lines 3 3 and 4`4 of Fig. l.

Figure 5 is a perspective view of one of the laths.

In the drawing above briefly described, I have shown a 'plurality of theimproved laths secured to studs S in the usual way, each lath beingindicated by the numeral 1. Each lath l is in the form of a lat woodenstrip of the same proportions as an ordinary lath, but opposite edges ofsaid lath l are formed with spaced elongated notches 2 which are rathershallow. The end walls of each notch are parallel with each other butextend obliquely of the lath, said end walls being indicated by thenumerals 3. The end walls 3 at one edge of the lath are in planes at anangle to the end walls at the other edge of said lath and hence it isinsured that adjacent edges of any two laths, shall not have their walls3 running in the same direction. By obliquely positioning these walls 3,acute angular corners the invention matter hereinthe descriptionaccompanying serial No. 685,224.

l are provided at opposite ends of each notch 2, one of these cornersbeing disposed at one side of the llath while the other corner is at theopposite side, and regardless of the way in which the lath is applied,one of these corners at each notch, is operable to form an eliectivelock behind which the plaster 0r the like keys.

The laths are applied in the usual spaced relation and consequently, theplaster P will form the usual keys K between adjacent laths, but due towill be formed with extensions E received in said notches. hind theforemost corners l of the adjacent laths and thus are effectively keyedin place.

Preferably, in the manufacture of the lath, I drive two lath nails ornails of other suitable size into one of its edges, as indicated by thenumeral 5, the headed ends of said nails being allowed to project theproper distance for accurately spacing the laths when they are applied.Thus, a wall may be lathed with much more speed and, accuracy than isnow possible with the ordinary wooden laths. In fact, the use Ol thesevspacers compels the workman to so apply the laths that a sulicient keyis formed to insure a permanent job. lVhile I preferably use nails forforming the spacer, any other suitable spacing means may be applied tothe laths to accomplish the desired results.

While I have shown and described the invention as embodied in anordinary wooden lath, it will be understood that the invention may belapplied to any size wooden strips and hence the term lath is not used inits limited commercial meaning.

As excellent results are obtainable from the details disclosed, they arepreferably followed, but within the scope of the invention as claimed,minor changes may be made.

I claim:

l. A lath comprising an elongated fiat strip of wood having shallowelongated notches in its opposite edges, the end walls of each notchbeing substantially parallel with each other but oblique to the lengthof the lath, the end walls of the notches at the notches 2, these keys iThese extensions lock beone edge of the lath being disposed in planes atan angle to the end Walls of the notches at the other edge of said lath.n

2. A. lath comprising an elongated flat strip of Wood having spacednotches each of which opens through an edge of and through atleast oneflat sidepof' the? strip, each notch being provided with opposed endwalls each of which is disposed at an acute angle to an external surfaceof the lath, 10

whereby to form locks for the keys formed by the plastic applied to thelath.

In testimony Whereo I have hereunto affixed my signature,

FRED M. sPAYD.
